Have you journaled and checked in about "head hunger"? I am five years out, 140# gone and no physical hunger sensations ever. I battle head hunger though. I'm "hungry" when I'm at my desk, when I'm physically weary, when I'm stressed, when I'm bored and when I'm distracted. I can be uncomfortably full and yet be "starving"
I've also learned that it's not just psychosocial hunger. Thinking about food, like trying to an healthy meals, can trigger head hunger. The game doesn't change, I just have a better tool to use to beat the enemy.
